A kind of re-reeler of producing the strip coil (R) of no central coiling mandrel has band and forms second winch spool (13) of the occlusal area that band therefrom passes through around first winch spool (11) of its driving with first winch spool.It is can be with respect to first winch spool movable and periodically shift to the surface of first winch spool to be provided with a movable part (21), band then is between the movable part and first winch spool, make band between the movable part and first winch spool, be subjected to punching press and braking like this, thereby tear band and make the free edge that band interrupts forming begin oneself's coiling.
Description
The present invention relates to produce the re-reeler of carrying material (as paper) volume, this strip coil does not have central coiling mandrel, that is to say not use the cylindrical support that is used to form strip coil.More particularly, this re-reeler that the present invention relates to comprises one first winch spool and one second winch spool, and band is driven around first winch spool, and second winch spool and the first volume form the occlusal area that band passes through around tube.
Italian patent the 1st, 201, an a kind of like this re-reeler is sent out in No. 220 descriptions, and in this patent, second winch spool can shift near band around its first winch spool that is driven.Contact between two winch spools is being torn band between the contact zone between volume that forms and tube.Owing to curling of the free edge of tearing generation input band, thereby described contact makes next strip coil begin to reel.
The shortcoming of this known devices is, the second movable winch spool has high inertia, limited greatly to carry out that band is torn operation and the speed of next band that begins to reel.This has influenced the feed rate of paper tape, thus limited re-reeler capacity rating.In addition, when reeling end, the bottom winch spool not only must be torn band, and the coiling band is rolled up to begin next, but also will unload the strip coil that just has been rolled into.Difficult in other words for unloading of above-mentioned motion and volume kept synchronously.
With italian patent the 1st, 201, compare for No. 220, the coiling of no mandrel strip coil is undertaken by central re-reeler, and in this re-reeler, band is to be wound on the central axle of special shape,, more above-mentioned axle is taken away after intact at strip coil.For example in US Patent the 4th, 487, this device has been described in No. 378.The said apparatus of coiling coreless roll and the distinct disadvantage of orthodox method are: the axle of the special shape that must take away by additional operations need be set, and this can influence the capacity rating of speed of production and factory.
US Patent the 3rd, 250 discloses the wind2 of a kind of heavy gauge band such as malthoid etc. No. 484.In this known devices, be provided with three winch spools, one of them winch spool has an anchor shaft, and two winch spools respectively have a movable axis in addition, make the strip coil increased in size but move apart the winch spool with anchor shaft gradually.When a coiled strip was reeled end, separated winch spool was stopped, and strip coil is removed from the winding area, makes winch spool close mutually once more.In this layout, a guide piece inserts the coiling space to begin the coiling of next strip coil.For this reason, band is at guide piece with have between the winch spool of anchor shaft and be directed to.Contact with two winch spools until its free end with movable axis.Because band keeps moving forward, the oneself winds up in the space that its free end begins to form between three winch spools and guide piece.After first lap forms, to reel and just between three winch spools, carry out, three winch spools then move apart mutually to form the formation space of strip coil, and guide piece is then removed from winch spool.
Said apparatus is unsuitable for production thin strip volume, and as paper roll etc., this is because in order to begin to reel the centreless band, and band must have impregnability to a certain degree so that form first lap.
The purpose of this invention is to provide a kind of later-model re-reeler, this re-reeler can overcome the shortcoming of conventional apparatus.
Specifically, even the purpose of this invention is to provide a kind of re-reeler that also can reliably cooperate in harmony under high band feed rate, above-mentioned band feed rate is generally 700 meters/minute or higher in paper product industry.
Re-reeler of the present invention will be characterised in that, be provided with a movable part that can move with respect to first winch spool, periodically shift to the surface of described first winch spool, so that between described movable part and described first winch spool, make the band braking, thereby band is torn, and band free end oneself is reeled.Therefore, band is torn (unless above-mentioned tearing finished by a kind of different mode) in the moment of braking by impact style.
The above-mentioned movable part that is used for beginning new coiling is removed, irrelevant with second reel, therefore, it has limited inertia, solid and can allow high acceleration/accel, so can carry out the utmost point short time, tear periodically one by one, thereby can realize high speed of production.In addition, because the operation that begins to reel do not undertaken by one of winch spool, thereby the latter can arrange to unload the strip coil of just having spooled and not influence the operation that begins to reel and the possible operation of tearing band.
Movable part is used for making band to tear so that begin next operating winding in the time of also can finishing at the coiling of a volume.This can brake between movable part and winch spool or actual punched web realizes.In fact, according to a possible embodiment of the present invention, movable part is pressed on the surface of winch spool, thus the punching press paper tape.Otherwise, for fear of wearing and tearing and limit mechanical stress, also can make movable part surface and winch spool shaping surface, thereby make it penetrate band betwixt and band is out of shape, thereby make band brake and be torn.
Tearing also of band can be by finishing with the self-contained process of irrelevant other of movable part.In this case, movable part only is used to begin the coiling of next volume.
The work of movable part also is used for the sort of embodiment that tears of band, has special advantage, so thereby it save and cut off or tear-off device.
Be used for being preferably disposed on the upstream of the occlusal area that forms by first and second winch spools at the movable part that predetermined point engages band and might be used to tear band.Movable part can have the surface that a cylindrical surface with first winch spool forms a space, so that can begin the coiling of strip coil in the upstream of the occlusal area that is formed by winch spool.Can before contacting second winch spool, the centreless strip coil begin the coiling of each centreless strip coil by this way.The surface of movable part (strip coil that is just beginning to reel is rotated on this surface by the rotation of first winch spool) is preferably tangent with the cylindrical surface of second winch spool.The progressively regular curved surface from movable part of this strip coil is transferred to the cylindrical surface of bottom winch spool.
In an embodiment with special benefits, make movable part around a rotational that overlaps with the second winch spool pivot center.
In another embodiment according to re-reeler of the present invention, re-reeler can be provided with one the 3rd movable diameter control winch spool, and this winch spool forms the coiling space with aforementioned two winch spools, finishes the coiling of centreless strip coil therein.
The present invention also relates to a kind of method that band (as paper etc.) is wound into coreless roll, wherein, band is driven so that rolling around first winch spool, when the coiling of a volume finishes, band is stamped between first winch spool and movable part, reels thereby the leading edge that makes band begins the oneself by the relative motion between the surface of the surface of first winch spool and movable part.Tearing of band best (but be not must) undertaken by the same movable part that begins to reel.
After understanding above-mentioned purpose of the present invention, by the understood in detail the present invention better of following detailed description.
In order to describe the present invention, following accompanying drawing is just represented preferred embodiment of the present invention, and obviously the present invention is not limited to these embodiment, and it be can be used for various modifications.

Figure 19 A and 19B are illustrated among the variable embodiment of width between centers between a kind of winch spool, two positions of winch spool.
Fig. 1 schematically represents the basic part of the re-reeler of first embodiment of the invention.N representative from large diameter volume (not shown) open around band, send to the winding area with the direction of arrow fN.The cylinder of band N is transferred in label 3 and 5 representatives, and label 7 and a pair of perforated drum of 9 representatives.Cylinder 7 is resting barrels, is carrying a phase blade, is mated action by the many blades on the cylinder 9 that rotates.Perforated drum 7 and 9 can be an any kind, and this specification sheets no longer is explained in detail.Band is delivered to first winch spool 11 from perforated drum 7 and 9, is driven around the first winch spool band.First winch spool 11 and second winch spool, 13 cooperatings, first and second reels form the occlusal area 14 that band therefrom passes.The downstream of occlusal area 14 forms a winding area, forms volume R in the winding area.Volume R contacts with first and second winch spools 11 and 13 and one the 3rd movable diameter control winch spools 15.With regard to the part of so far having described, the operation of re-reeler is a traditional type, for example discloses in the relevant German patent DE 3225518 with it of the GB2105688 of British patent.
Around the articulated movable part 21 of the axis A-A of bottom tube, it is used for tearing band when the coiling of volume R finishes, and need not the coiling that central tubular core promptly begins next volume.In the illustrated embodiment, movable part 21 is driven by a rocking arm 23, the push rod 25 and cam 27 cooperatings of rocking arm.But the driving of movable part 21 also can realize in another way, for example, by independently, the suitable motor of control or realize by other actuating device.
Fig. 2 represents an intermediate steps of the coiling of coreless roll R.As shown in Figure 2, volume R contacts with three winch spools of anticlockwise motion.The circumferential velocity of these winch spools equals the feed rate of band substantially.Movable part 21 is in lower position with respect to winch spool 11, to avoid influencing sending to of band N.
When volume R when reaching preliminary dimension (being defined as the function of length of the band of diameter and/or coiling), movable part 21 is shifted near first winch spool, as shown in Figure 3, this motion obtains by cam 27, cam 27 anticlockwise motions, each coiling cycle rotation one circle just says that also a volume of every formation R rotates a circle.In shown in Figure 3 the setting, the surperficial 21s of movable part 21 is very close to band N, but do not touch band.
Torn at band N, the moment that the coiling of next volume must begin, movable part 21 moves to position shown in Figure 4 from position shown in Figure 3 suddenly, and on this position, the surperficial 21s of movable part 21 contacts with band.This moment, the band pressurized that is to say that band is subjected to punching press between the cylindrical surface of the described surperficial 21s and first winch spool 11.This punching press action at first makes band tear along a perforation line between the contact point of movable part 21 and band and the volume R that just formed.The second, between the surface of surperficial 21s and winch spool 11, make the front portion (promptly near the part of tearing that section) of band curling to the punching press of band action.Detailed this situation of having shown in the enlarged drawing of Fig. 4 A.
See Fig. 4 A in case band has formed a circle S(), the surperficial 21s of the rotation of winch spool 11 and movable part 21 begins the coiling of next volume with separating slightly of the cylindrical surface of winch spool 11.Next twists in the periphery of winch spool 11 and the concave surface 21c(of movable part 21 sees Fig. 5) between begin to form in the coiling space that forms.Volume can be kept and the contacting of the cylindrical surface of the concave surface 21c and first winch spool 11, thereby the diameter of coiling is increased gradually.In some cases, face 21c can be flat, for example has in the situation of limited extension at face 21.
Because the anticlockwise motion of winch spool newly twists in concave surface 21c and goes up rolling, (sees the new volume R among Fig. 5 thereby make in the process that newly twists in formation to advance
1).New volume R
1Speed of advance equal half of band N feed rate.As shown in Figure 5, under these conditions, movable part 21 remains static, and spaced apart with the cylindrical surface of winch spool 11 slightly, and Fig. 3 illustrates identical situation, thereby band can freely be sent to.
The shape of concave surface 21c makes the cylindrical surface of itself and second winch spool 13 tangent, therefore, and the new volume R in forming process
1Can not be subjected to stress successfully from moving to and the contacted position of the cylindrical surface of second winch spool 13, thereby occupy position shown in Figure 6 with concave surface 21c position contacting.From this position, make volume R
1By winch spool 11 and 13 and the space that forms of diameter control winch spool 15 in advance, the volume that forms in last circulation has left above-mentioned space, and the edge draws off slideway 29 and unloads.
The volume R that spools draws off and newly rolls up R
1The handover that enters the coiling space that is formed by three winch spools by occlusal area 14 realizes by speed discrepancy.Specifically, roll up the acceleration that to control winch spool 15 by diameter that draws off of R, perhaps, perhaps realize by the resultant effect of above-mentioned two velocity variations by the deceleration of second winch spool 13.If winch spool 13 is slowed down, this action just can be used for finishing the rouleau R in forming process
1Enter the introducing in the coiling space that forms between winch spool 11,13 and 15 by occlusal area 14.For example, in US Patent the 4th, 478, the process that draws off of the volume of having described to spool in No. 377, and the volume that is forming inserts the process in coiling space.As described in European patent EP-A-O331 378, also can realize the volume R that forming by the unmodified speed discrepancy of winch spool 11 and 13
1Insertion process.In this case, the width between centers between winch spool 11 and 13 is changed.
For the ease of drawing off the volume R that spools, also can use a mobile slideway 29 that temporarily shifts near volume R.
As volume R
1When having broken away from the contacting of concave surface 21c, can make movable part 21 away from winch spool 11 to position that Fig. 2 increases, thereby prevent that it from interfering sending to of band N.
As mentioned above, movable part 21 can be handled without cam 27 by motor independently.When using cam 27, cam 27 can drive by a transmission gearbox, and this transmission gearbox can obtain motion from the central engine installation of re-reeler, perhaps by the axle of described cam 27 keyed jointings of motor direct-drive independently.
The surface that contacts with band 21 of movable part 21 with can scribble the elastic buckling material and whenever winding off the formation of beginning coiling hour circle S so that improve.As a kind of replacement scheme, perhaps as a kind of measure of carrying out simultaneously, the surface of winch spool 11 can scribble compliant material such as rubber.Cylindrical surface at the surperficial 21S and/or first winch spool 11 can be coated with to have the material of great friction coefficient, so that further help beginning the coiling of every volume.
In graphic preferred embodiment, re-reeler is provided with a pair of perforated drum 7,9.This is not rigid needs, but when being provided with like this, the swing of movable part 21 will keep synchronously with cylinder 7,9, thereby it is last that movable part 21 and contacting of winch spool 11 are appeared at apart from a limited distance of the perforation line in downstream, contact zone, occurs on the described perforation line thereby make to tear.
In Fig. 1 to 7 illustrated embodiment, band N tears by the interoperation of movable part 21 and winch spool 11.But this is not rigid regulation, but this scheme can make the structure of re-reeler more simple.
Fig. 8 represents a kind of feasible embodiment according to re-reeler of the present invention, and wherein band N cuts off or tears in the upstream of movable part 21.Identical identical with Fig. 1 to the 7 or corresponding part of piece number representative.Different with Fig. 1 to 7 is, embodiment illustrated in fig. 8 have one and cut off device, and shutoff device shown in Figure 8 has a cut-out cylinder 51 that has section 53 or other cut-out element that is equal to.Cylinder 51 rotates synchronously with winch spool 11, and in the moment of being scheduled to, blade 53 and winch spool 11 lip-deep flute profiles are blade 55 cooperatings mutually.This point can be by making cylinder 51 shift near the mode (as US Patent the 4th, 487, No. 377 described) of winch spool 11 or going up removal blade 53 modes (as italian patent the 1st, 213, No. 822 described) by the seat that forms from cylinder 51 and realize.Content this paper of above-mentioned two patents is incorporated by reference.
In this example, on winch spool 11, be provided with a series of suctions hole 57, so that after band is disconnected the work area that moves to movable part 21, maintain the leading edge of band at least.Next door 59 in winch spool 11 defines a vacuum chamber.
Also available other method of band separately.For example, thus band applied tension force make its disconnection by quickening diameter control winch spool 15.Tearing along a perforation line 9 in this case forms, as shown in Figure 9.Make movable part 21 contact and more easily to tear with band N.
The concave surface 21c of movable part 21 can make the size of the volume R that forms in its adaptive space that is being limited by concave surface 21c and winch spool 11 when forming.Apply one deck compliant material or adopt a kind of system that has flexible belt or like along the expansion of movable part 21 or the formation of concave surface 21, just can realize this point.This embodiment as shown in figure 10, wherein, concave surface 21c ' is formed by a belt around two cylinder 21R operation.Can prevent the slip of belt concave surface 21c ' in above-mentioned layout by belt being anchored in one of cylinder 21R, but this can make the volume R in the belt reason forming process
1Be applied to the power on the belt and be out of shape.Substitute endless-belt, can use a kind of open belt, the one end is anchored in an attachment point, and the other end then is anchored in (for example) elastic restraint part.
In the various embodiments described above, all mention winch spool 11, it has an outside continuous surface, and the surperficial 21S of movable part 21 is pressed on this surface, so that punched web.Because the mechanical contact that advances to connect between movable part 21 and the winch spool 11, thereby this mode of operation means mechanical strees repeatedly.
For fear of above-mentioned mechanical action repeatedly, thereby avoid stress and wearing and tearing, (according to Figure 11 of the present invention and 12 illustrated embodiments) can be provided with many circular groove 11S on winch spool 11.Then be provided with many protruding 21D that are oppositely arranged with circular groove 11S winch spool 11 on the surperficial 21S of movable part 21.When beginning for the coiling that forms new volume, movable part 21 is shifted near winch spool 11, make protruding 21D enter circular groove 11S at least partly, as shown in figure 12.This makes band N in laterally (being the axis of close wind tube 11) upward distortion, as shown in figure 12, therefore, produces rubbing effect on band.This friction is enough to make band to tear (unless this tearing realized by other process) along a perforation line, and the beginning oneself reels to form a new volume thereby the free edge of band curls.In this case, in order to be increased in the grip effect on the band, all constitute on two surfaces of protruding 21D and winch spool 11 by the material of great friction coefficient.
The embodiment of a kind of variation of Figure 13 to 16 expression.
At first consult Figure 13 and 14, label 111 is represented first winch spool, and the band N that forms strip coil R is around operation thereon.Label 113 is represented second winch spool, forms an occlusal area 114 with first reel.The equal anticlockwise motion of two winch spools (seeing Figure 13).Label 115 is represented the 3rd winch spool, also is anticlockwise motion, and removable, and the diameter of the volume R in the forming process can be increased and be controlled.The 3rd winch spool 115 is by one arm 117 carryings, and arm 117 is connected in the re-reeler structure by pivot 119.
Supporting members 155 supportings that axle 151 is come by many intervals,, 155 of supporting members are by movable component 131 carryings.Coil on 157 axles 151 that are bonded between the supporting member 155, each dish 157 is supporting a pivot 159, and idle running twelve Earthly Branches are holding a trundle 161 on it.Trundle 161 and one are fixed in steel tubular piece 163 cooperatings on the plate 165, and plate 165 is then made by light flexible material such as carbon fiber.The assembly that label 121 representatives are made of tubular piece 163 and lamination 165.Lining 167 is made by elastic buckling material such as rubber etc., is fixed in lamination 165.The curved surface that label 121A deputy activity spare 121 forms, movable part 121 constitutes the passage that a cross-sectional plane increases with the cylindrical surface of winch spool 111, begins to form the coiling of each strip coil in this passage according to following process.
A pair of arm 71 is articulated on the axis A-A, and around axis A-A, winch spool 113 rotates, movable component 131 swings.Figure 13 one arm 171 that only draws, one arm 171 is arranged on the opposite side of re-reeler symmetrically in addition.The doffer of an idle running is installed on every arm 171, constitutes the push rod of respective cams 139.Under normal service conditions, a cylinder-piston system 175 makes arm 171 pushings one adjustable strut 177, and pillar 177 is positioned on the frame, promptly fixes with respect to the pivot center of winch spool.The setting device that starts pillar 177 can change the interference situation between the surface of winch spool 111 surfaces and movable part 121.
When re-reeler was worked, winch spool 111,113 and 115 rotated the rotation with the volume R that keeps forming in the same way.When volume R is rolled into, movable part 121 shifts near the surface of the winch spool 111 that band driven thereon, band is subjected to punching press or is braked by any way between the surface of the surperficial 121A of movable part 121 and winch spool 111, thereby band is torn between punching press point and the volume R that is rolled into, and the free end of the band of tearing is rolled and is begun the oneself and reels so that form new volume.
The process that aforesaid operations carries out is similar to contrast Fig. 1-7 detailed description of being done, and this paper repeats no more.
But, be that with the difference of fwd embodiment the convergence motion between movable part 121 and the reel spool 111 can be carried out in two steps.In fact, in the winding process that forms volume R, motor 133 is to keep static.When also having a certain amount of band must be when going up near the volume R that finishes, motor 133 be activated with the rotating speed that the rotating speed with re-reeler is directly proportional, and it moves through belt 135 and reaches twin cam 139.。The profile of cam can cause the motion of assembly 131 around axis A-A, thereby makes movable part 121 surface of convergence winch spool 111 gradually.For each circulation of reeling, that is to say, in the forming process of each volume R, the speed that cam 139 is directly proportional with the speed with band is changeed a whole circle, stops then, is waiting for and is doing next circulation, therefore, in each coiling cyclic process, movable part 121 shifts near winch spool 111, and then removes from it.But the motion that obtains by twin cam 139 does not make the surface of surperficial 121A and winch spool 111 lean on too closely down to causing tearing of band, make again subsequently strip coil around.In fact, though the rotation of twin cam 139 causes the convergence gradually of winch spool 111, the motion of motor 133 also is passed to axle 151, thereby is passed to around the rotational of axle 151 and the trundle 161 that flexure strip 165 is swung with respect to assembly 131.The convergence motion that convergence motion that maximum convergence forms by twin cam 139 constantly is superimposed on sheet 165 takes place in the cylindrical surface of surface 121A and winch spool 111, and back one motion causes by trundle 161, and trundle 161 is by axle 151 drivings and rotate.
As clear expression in Figure 13 and 14, the diameter of belt pulley 141,145 is than the diameter of driving pulley 137 much bigger (general big four times), and the diameter of belt pulley 137 approximates the belt pulley 148,150 that is bonded in axle 151 greatly.In other words, at the revolution of twin cam 139, thereby in the coiling circulation that forms volume R, a sub-assembly 131 can occur and level off to the swing of winch spool 111, and movable part 121 is with respect to the quick swing of assembly 131.When belt pulley 133 and 148,150 has same diameter and belt pulley 141,145 when the diameter that is four times in belt pulley 133 is respectively arranged, in each circulation of reeling the swing of one sub-assembly 131 and the swing of four movable parts 121 can appear.The mutual PHASE DISTRIBUTION of above-mentioned swing makes that the quick swing of movable part 121 for once temporarily overlaps with the maximum convergence point of assembly 131 with respect to winch spool 111.
Therefore, said apparatus makes the motion of movable part 121 trend winch spools 111 can be divided into two motions, and first is low-tach slowly convergence (by twin cam 139 controls) roughly, and second is meticulous fast convergence (by trundle 161 controls).This can reduce relevant inertia greatly, and this is owing to provide the movable part of the periodic motion of upper frequency to be made up of the part that quality greatly reduces.In contrast, the heavier part of constituent components 131 is done slow four times motion, thereby has small inertia stress.
Consult Figure 15 and 16 now, as shown in the figure, lamination 165 is anchored in the front portion 183 of the suitable shape of supporting member 155 by one group of screw, and supporting member 155 then is fixed in movable component 131.One pectination part 185 also is fixed in front portion 183 by screw 184, and pectination part 185 is provided with many teeth 187 that extend in the circular groove 189 of winch spool 113.Figure 15 is the expression pectination part view of looking along the arrow F of Figure 13 separately, and the label of tooth is 187 in the figure.The pectination part constitutes the surperficial 185A that surperficial 121A extended of movable part 121 in addition.
Therefore, the smooth surface that the scroll that the confession that pectination part 185 provides does not have projection is forming is moving, thereby above-mentioned volume can successfully be rolled into the cylindrical surface of winch spool 113 easily from the surperficial 121A of movable part 121.In addition, if the volume that is forming 113 the process from surperficial 121A to winch spool is not that (this is incidental situation to the axis that is parallel to winch spool 111 and 113 well, because of there not being the central core shaft of strip winding material), so, pectination part 188 can make rolling off cleaved surface 121A, and 185A makes its aligning during to winch spool 113 automatically.In fact, if the volume axis tilt in the axis of winch spool 113, so Juan forefront will than still contact with surperficial 185A contract most after part contact winch spool 113 in advance.On the other hand, because the speed of the cylindrical surface of winch spool 113 superficial velocity of winch spool 111 no better than, and surperficial 185A is static, the forefront of volume can automatically slow down.Have only when the axis of volume is parallel to the axis of winch spool 111 and 113 well, the various piece of volume just can obtain along the identical translational velocity of winch spool 111 with 113 occlusal areas that form.
Can promote the volume that forming alignment actions with respect to the winch spool axis by the rotating speed with respect to first winch spool of appropriate change second winch spool.For example, utilize among centring control assembly 191(Figure 13 and schematically draw) winch spool 113 is slowed down gradually with respect to winch spool 111, thus make the occlusal area of volume that is forming by forming between winch spool.If above-mentioned deceleration is delayed a bit with respect to being rolled onto the moment that reaches the transition region between pectination part 185,187 and winch spool 113 surfaces, volume will occur and tend in itself and two winch spools, 111,113 contact position maintenances static moments.In this moment,, then can realize the aligning of rolling up just if volume is not aimed at the winch spool axis is fine.In this case, take measures to make winch spool 111,113 to leave mutually.
No matter the process of the rotating speed of control winch spool 113 how, the possibility that can provide winch spool 111,113 to shift near mutually, move apart.For example, the motion of moving gradually by winch spool 111,113 axis can make constant airspeed between the winch spool 111,113 or variable, and does not make volume not stop (that is to say, make to twist between the winch spool 111,113 and advance continuously gradually).Above-mentioned motion of moving gradually can be by a driver control, and perhaps the elasticity song that causes by the increase of the volume that is forming allows and realizes.Figure 19 A and 19B represent an alternate embodiment, and wherein, winch spool 111,113 is at volume R
2On two positions after the leaning in occlusal area 114 in the mobile step.In this embodiment, winch spool 111 and 113 is separated gradually by actuator 116, and actuator 116 is connected in the fork 118 of a pair of carrying winch spool 111, sees one of fork 118 in the drawings only, and another fork is symmetry with it.
One elastic component 120 is connected in arm 118 with actuator 116.Winch spool 111,113 contract after mutually and once more the approach-ing controlled motion obviously also can realize by the displacement of winch spool 113 with respect to winch spool 111, the axis of winch spool 111 is static, but this means and must also make the shortcoming of swing component around the axis shift of winch spool 113.
The mutual displacement of winch spool is subjected to sufficient restriction, also can not cause the deleterious effect to strap tension when both having made the winch spool of displacement be winch spool 111.
Centring control assembly 191 also can be used for control: the dipping and heaving of movable diameter control winch spool; The possible acceleration of described winch spool is so that unload the strip coil of finishing; The motor 133 that is used for the swing of control assembly 131; And also may control the actuator that comes in decision winch spool 111,113 spaces.
Figure 17 represents the embodiment according to a variation of re-reeler of the present invention.Label 221 representatives are articulated in the movable part of the pivot center A-A of bottom winch spool 113.The label of top winch spool and the 3rd winch spool is respectively 111 and 115.Beginning the circulation time of reeling, the label of the rolling surface of strip coil is 221A.Label 285 is represented a pectination part, and is similar to part 185, also is provided with the tooth 287 with winch spool 113 cooperatings.R
1Be illustrated in the volume that is rolled in the process of unloading, R
2Representative is at the volume of the first volume in step.
In this embodiment, the convergence motion between the surperficial 221A of movable part 221 and the cylindrical surface of winch spool 111 also was divided into for two steps, but its process is different from last embodiment.In fact, movable part 221 is moved by a disk 231, and disk 231 rotates around axis 233, and is flapped toward by cylinder-piston or equivalent system by an eccentric pivots and constitutes elastic component 237, and elastic component 237 is articulated in the annex 241 of movable part 221 at 239 places.In fact, system (231,233,235,237,239,241) is a two-fold, is arranged on two body side frames of re-reeler.The rotation of disk 231 causes motion around axis A-A by the part 237 as connecting rod.To 111 maximum convergence moments of winch spool, arm 241 contacts with an adjustable strut 243 at movable part 221.The position of pillar 243 can be adjusted, thereby just by disk, the crank mechanism that pivot 235 and elastic component 237 formed be in outer dead center or even the moment before outer dead center, above-mentioned convergence is taken place, in this case, the elasticity of the pneumatic spring that is made of cylinder-piston system 237 of remaining stroke is cushioned.In any case, in the moment that arm 241 contacts with pillar 243, when part 245 footpath of winch spool 111 is outwards moved and realized in the last high speed approach procedure that the some 221S on movable part surface does not contact with the surface of winch spool 111.For example by a kind of italian patent the 1st, 231 that is similar to, the mechanism described in No. 822 (its content is as the part of this specification sheets) can realize the radial motion of part 245.The retract motion of part 245 can take place in the rotation process before the contact of practicality, and can take place in the rotation process before the contact of practicality towards the return movement of dead position, and can carry out in the rotation that continues towards the return movement of dead position.The quality of part 245 will suitably limit guaranteeing the retract motion on time in this time gap, thereby when part 245 during by movable part 221 the place aheads, realizes the contact between the surperficial 221S of the outside face of part 245 and movable part 221.
The interruption of band N also can realize by a shutoff device that is arranged on movable part 121 or 221 downstreams when a coiling loop ends, for example, a groove cooperating that is carrying blade cuts cylinder and winch spool 111, a suction device are being fixed the free edge in otch downstream and it are being shifted to movable part 121 or 221.In this case, above-mentioned movable part is towards being to make the free edge of band roll and begin to form the coiling circulation of new volume around tube 111 approach-ing sole purposes, and above-mentioned convergence must be at above-mentioned free edge through the maximum convergence point back generation between winch spool 111 and movable part 121 or 221.
Yet for simplified structure, as shown in drawings, movable part 121 or 221 and the part punched web N of winch spool 111 produce brake action and tear, so separately band is the scheme of recommending.In this case, make the friction coefficient on the longitudinal component on winch spool 111 surfaces be in friction coefficient less than the motion of feeding strip of sheet material relatively out and away, help tearing of band near the surface in downstream.For example, in the embodiment shown in Figure 17, moving part 245 can be provided with two different outer surface part 245A and 245B.Surface 245A friction coefficient is lower, can be a smooth surface for example, and surperficial 245B friction coefficient is higher, for example can be made of one deck emery cloth, and its friction coefficient equals even greater than the friction coefficient of the remaining surface of winch spool 111.This layout has been arranged, the motion by suitably making movable part 221 and part 245 and the position of the perforation line on the band N keep synchronously, a perforation line is on the surperficial 245A when movable part 221 contact portions 245 just, or abuts on surface 245A downstream, and between movable part 221 and surperficial 245A punched web.This make band on surperficial 245A, slide (because of its friction coefficient low due to), thereby tear band along perforation line.Rolling and beginning of the band free edge that forms after the surperficial 245B of the great friction coefficient that is right after thereafter and comes helps tearing reeled.
Above-mentioned make design that band is convenient to tear also applicable to the described embodiment of Figure 13 by winch spool 111 roughness of surface characteristics, on the winch spool 111 directly rather than on its moving part, form two kinds of surfaces with high and low-friction coefficient.
When winch spool surface begins to contact with the movable part surface and makes the band interruption and/or when beginning to reel, band has the tendency that fluffs in the contact point upstream.But setting device is in case lose the tendency of tension force in band upstream formation kind.A kind of appropriate device of establishing for this purpose comprises a trundle, makes it contact band in band is driven to zone on first winch spool, and trundle can be motor-driven, also can dally.This trundle is shown in broken lines in Figure 13, and label is 301.Contact preventing between winch spool 111 and trundle 301 band fluff in the winch spool upstream.
Also the device that another kind prevents that band from fluffing can be set, many suctions hole 303 promptly is set on the cylindrical surface of winch spool 111, these inhale the hole makes on the surface of band attached to winch spool 111.This technical scheme is shown among Figure 17.Obviously above-mentioned two kinds of technical schemes are interchangeable, also can use together, also can be separately or be applied to together among each embodiment shown in the drawings.When using the suction hole, the vacuum in the hole 303 can be interrupted with any known mode in good time.
The horizontal rouleau that downcuts of strip coil that Figure 18 schematically draws and makes from above-mentioned re-reeler.As shown in figure 18, rouleau does not have central core shaft, wherein without any hole, is not free middle section, abrim band yet.Specifically, the density of circle is big in the middle section S1 of volume, that is to say and roll up tightly, and the density of circle is little in more outer region S 2.Region S 1 is to move in the passage that the surface by surperficial 121A or 221A and winch spool 111 forms and form.Region S 2 is between winch spool 111,113, is wound between winch spool 111,113 and 115 again afterwards.The diameter of the region S 1 of rolling up tightlyer is in 1 to 20mm scope.
Above-mentioned re-reeler can be used to produce strip coil, as paper roll, for example produces the toilet paper of rouleau, high-mobility, multipurpose, wheeled vehicle cleansing tissue or the like.Paper tape can be one or more layers, and can use any technique known as calendering, impression etc.
The present invention obviously also can present other concrete form and not exceed scope of the present invention, and the various embodiments described above are descriptive and be not determinate.Scope of the present invention is defined by the claims.
